Sunil Dutt also said, "When I was struggling with the troubles related to the arrest of my son Sanjay Dutt and my house was repeatedly being searched by means of numerous police raids, Rajendra Kumar was the one who came to my rescue by staying at my house and ensuring that raids were conducted using due procedures, false evidences were not planted in the house and valuables were not stolen."
